Abstract

We evaluated in elderly subjects a the ability of GFR formulas to discriminate chronic kidney disease CKD, b the correlation between renal morphology and function, and c the usefulness of combined r-US and GFR formulas to detect CKD. A total of 72 patients were enrolled mean age 80 ± 7 years, male sex 44%, serum creatinine 0.98 ± 0.42 mg-dL, and CKD 57%. Cockcroft-Gault showed the highest sensitivity 78% and specificity 94% for CKD and was correlated with kidney volume , . All formulas failed to provide a reliable estimate of GFR. In multivariate analysis, Cockcroft-Gault < 52 mL-min and kidney sinus section area < 28 cm

showed the highest accuracy for the identification of CKD subjects AUC 0.90, . MDRD and CKD-EPI differed significantly for GFR ≥90 mL-min. Conclusions. Cockcroft-Gault < 52 mL-min was able to discriminate subjects with CKD but all formulas failed to provide a reliable estimate of GFR. The combined use of r-US and Cockcroft-Gault formula improved the ability to discriminate CKD in elderly subjects.
